代碼說明：

1、對視頻的后綴格式做了簡單的校驗，如果需要調(diào)整可以自己調(diào)整一下。

2、對輸出的結(jié)果做了處理，輸出int類型的數(shù)據(jù)，方便使用。

驗證一下

準備的視頻如下：

補充

Python實現(xiàn)獲取視頻fps

代碼說明：

1、首先對視頻格式做了簡單的判斷，這部分可以按照需求自行調(diào)整。

2、通過subprocess進行命令調(diào)用，獲取命令返回的結(jié)果。注意范圍的結(jié)果為字節(jié)串，需要調(diào)整格式處理。

驗證一下

下面是準備的素材視頻，fps為25，看一下執(zhí)行的結(jié)果。
